IsError = false;
throw new Exception(Erp3s.Resources.Strings.ResourceManager.GetString("Display Name is required",Culture));
}
\_displayName = value;
OnPropertyChanged("DisplayName");
}
}
private readonly ObservableCollection<ValidationError> \_errors = new ObservableCollection<ValidationError>();
public ObservableCollection<ValidationError> Errors
